Suspension Performances Analysis of A Novel Bearingless Switched Reluctance Motor

In this paper, a novel bearingless switched reluctance motor (BSRM) is proposed, in which the independent torque magnetic circuit and torque magnetic circuit are adopted. The natural decoupling between the suspension force and torque are obtained. Firstly, the configuration and suspension principle are introduced, respectively. Secondly, the mathematical models of radial suspension force are established according equivalent magnetic circuit. Finally, the main parameters are designed. The three-dimensional finite element analysis is carried out to calculate air gap magnetic fields and radial suspension forces. The research results prove the correctness of the structure, suspension principle and mathematical model of the new BSRM.
